RONALD W. CATTO, OF TORONTO, ONTARIO, CANADA CONCEALED HEATING FORBATHROOMS Application led November 5, 1930. Serial No. 493,541.

In modern homes, generally speaking, and which terminates at its upperportion in a in many apartment houses, the bathroom flange 4. Thisflange is substantially horiis very small in size, and this room is in-Zontal, and terminates in a downturned edgevariably heated by means oteither a hot air tiange 8.- is the wall placed in spaced res ductopening thereinto, or else by means of lationship 1n respect of thewall3, and the 5a radiators of various types. When radiators shape andconstruction of this wall may vary are used, they are either placed in arecess within a wide range, provided it 1s adapted in a wall ot theroom, or else placed in some to permit circulation of air therethroughinto convenient part ot the room. In this latter the said chamber,without departing from the nl case, the radiator occupies space thatshould spirit of my invention. I preferv to form this te be availablefor use by the occupants of the wall with a horizontal top flange 6which eX- house. In the other case,the countersinking, tends inwardlyin' contact with the lower so to speak, of the radiator in the wall of aedge of the flange 8, and terminates in a room, adds to the expense ofconstructing the Vertical edge-flange 7 which rests underneath .l

V wall. And in both cases the exposed radiathe flange 4 and'in contactwith the inner side 65 tor mars the appearance et the room. of theflange 8. This construction lends it- Now one of the objects of myinvention is self for packing so astoprevent water getting to utilizewhat is at present practically waste between these parts. As shownclearly in space in a bathroom within which to locate Figs. 1 and'3,the'spaced relationship ot' the 1 the heating means for the room, and atthe wall 5 inv respect ofthe wall 3 provides a i same time positivelypromote circulation of chamber within which, having regard to Fig. theheated air therein into the roem, and in 1, is placed the radiator 11,which may be of the following specication and the drawings any suitabletype. The air to be heated forming part thereof, I shall disclose onepasses into this chamber through the apery .en form of my invention, anda modilication tures 12 and thereout of through the apertures 75thereof, and what I claim as new will be set 13. Thus it will be seenthat positive circutorth in the claims forming part ot this specilationot the air through this chamber is proication. vided for, and thiscirculation will positively Fig. 1 is a cross section through one formpromote the circulation of the air 1n the room. -IH ot standard bathtubshowing a radiator posi- Any suitable means may be employed to reantiened in a chamber located at one side of the tain the wall 5 inposition. For example` tub.

Referring to the drawings, 2 is the bath- Although I have shown thewalls 5 as rest- .1.00

"" tub, and the same is provided with a wall 3, ing in contact with theiloor, these walls may be supported at their bottom portions in spacedrelation to said floor, thus permitting me to omit the apertures 12 andyet provide for the circulation of the heated air through the saidchamber.

Since the space now occupied by the radiator is available for use by theoccupant of the bathroom, by means of my invention, I have, in effect,increased the size of the room. Another advantage flowing from myinvention resides in the fact that since the heated air circulatesthrough the chamber between the Walls 5 and 3, it will pass into theroom Well removed from any of the Walls thereof, thus avoiding themarring of these Walls.

Various changes in details of construction Will suggest themselves toone skilled in the art, Without in any manner departing from the spiritofy my invention.

What I claim as my invention is:

l. The combination With a bath tub having an outwardly directedhorizontal top flange terminating in a relatively short downturned edgeflange spaced from the Wall of the tub, of a floor supported verticalWall associated with the upper edge flange of the tub and located inspaced relation to the Wall of the tub to form a chamber for housing afloor supported radiator, said Wall having grille areas therein topromote the circulation of heated air through said chamber into a room,a horizontal flange at the upper edge of the vertical Wall directedtoward the Wall of the tub, disposed beneath and engaged With thedownturned edge flange of the tub and an upvvard ly extending edgeflange on the free edge of the Wall flange disposed inwardly of andcontacting the downturned edge flange of the tub to provide aninterlocking connection between the tub and Wall.

2. The combination with a bath tub having an outwardly directedhorizontal top flange terminating in a relatively short downturned edgeflange spaced from the Wall of the tub, of a floor supported verticalWall associated with the upper edge flange of the tub and located inspaced relation to the Wall of the tub to form a chamber for housing afloor supported radiator, said Wall having grille areas therein topromote circulation of heated air through said chamber into a room, anda flange at the upper edge of the vertical Wall directed toward the Wallof the tub With the free edge of the Wall flange interlockingly engagedwith the inner side of the downturned edge flange on the tub Wall.
